I drew this on chemsketch - http://img413.imageshack.us/my.php?image=peptide1kn3.jpg I am trying to figure out what the results would be... there are 3 peptide bonds here... where would the reaction take place? the first, second or third peptide? My guess would be that I could do the...

do you know any other names for atp?

I have a few questions about ATP. what are the systematic names of ATP? are they the IUPAC NAMES? answer: 5-(6-aminopurin-9-yl) -3,4-dihydroxy-oxolan-2-yl methoxy-hydroxy-phosphoryl oxy-hydroxy-phosphoryl oxyphosphonic acid where can I find some information about reaction of ATP...

right... i don't think i put electrons in the antiboding orbitals for LiF

ok... i will delete some electrons from the MO.

here it is.

ok i tried to fix it... i really hope this is right. please let me know if i am doing it right now. thanks.

yes i am... can you help?

how do you draw the energy level diagrams for LiF molecule? i know how to draw an energy level digram for Li but how do you do it for a molecule?

i have two questions... does an electron have a continuous range of energies? I think the answer is no. am i right? and also... what does the solution of the schrodinger's equation provide?

ok thanks!... I wasn't sure if the answer was = 8.3*10^-10 J*s/m or 8.3*10^-10 Newton seconds because of the units...

Can someone please check over my solution and let me know if its right or wrong? Thank you. question:calculate the momentum if the energy of photon is 25 x 10^5 erg? solution: 2500000 Ergs = 0.25 Joules p=E/c (0.25 J)/(3*10^8 m/s)= 8.3*10^-10 J*s/m

ok so... if i want to calculate the momentum if the energy of photon is 25 x 105 erg I would get... p=E/c (25*10^5 erg)/(3*10^8 m/s)= 8.3*10^-3 erg*m/s is that correct? thanks!

ergs - yes units of energy. what do you mean rearranging the equation? Einstein equation is e=mc^2?

how do you calculate the momentum if the energy of photon is 25 x 105 erg? i know p=mass*velocity but i am not sure how to do this problem. is the SI units of photons... erg? i just want to make sure.
